Which of the following practices does not conserve water?a.Avoiding water wastageb.Rainwater harvestingc.Improving irrigation efficiencyd.Groundwater extraction

The practice that does not conserve water among the options provided is d. Groundwater extraction.

Here's why:

a. Avoiding water wastage: This is a direct method of conserving water. By not wasting water, we are effectively conserving it.

b. Rainwater harvesting: This is a method of collecting and storing rainwater for later use, rather than allowing it to run off. It is a sustainable practice that helps in water conservation.

c. Improving irrigation efficiency: By improving the efficiency of irrigation, we can reduce the amount of water wasted in agricultural practices. This is another method of conserving water.

d. Groundwater extraction: This is the process of taking water from a ground source, either temporarily or permanently. This practice does not conserve water, but rather depletes it. Over-extraction can lead to a decrease in groundwater levels, drying up of wells, reduction of water in streams and lakes, and degradation of water quality.
